Abstract
The lettering pen that a kind of ink circulates of annotating uses.At the air bag that the bonding film of pen core tube inner wall is made.Form an annular seal space between tube wall and air bag, can prevent ink from volatilizing and go bad, preventing ink from spilling.Air bag volume, along with air pressure change, keeps pen core inside and outside air pressure balance, reaches uniform effect out of ink when writing.When being finished ink, eject connector with sheath, to oil pipe filling ink, connector is turned back to oil pipe can be write.
Description
Art
The utility model relates to a kind of lettering pen, the lettering pen that ink circulates of especially annotating uses.
Background technology
At present, gel ink pen structure market occurred is made up of nib, oil pipe, ink, lithium saponify tail plug.Wherein fill ink at oil pipe, oil pipe afterbody lithium saponify seals.Be subject to pipe aperture restriction, contained quantity of ink is little, and ink of can not annotating, and write ink just discarded, pen core material recovery processing cost is high, and natural degradation takes 200 years, and metal and grease can contaminated soil and water.
Summary of the invention
Can not to annotate ink and the deficiency that recycles to overcome existing lettering pen, the utility model provides a kind of lettering pen, and this lettering pen is when writing ink, and ink circulates of can annotating uses.
The utility model solves the technical scheme that its technical problem adopts: at the bonding air bag be made up of film of pen core tube inner wall.Form an annular seal space between tube wall and air bag, can prevent ink from volatilizing and go bad, preventing ink from spilling.Air bag can regulate the air pressure inside and outside pen core automatically, and when writing, ink reduces, and air bag becomes large, and annular seal space diminishes; When annotating ink, ink increases, and air bag diminishes, and annular seal space becomes large.Keep pen core inside and outside air pressure balance, reach uniform effect out of ink when writing.When being finished ink, eject connector with sheath, to oil pipe filling ink, connector is turned back to oil pipe can be write.
The beneficial effects of the utility model are, when ink is finished, ink circulates of can annotating uses, and reduces use cost, also solves the problem that the wasting of resources and waste material pollute simultaneously.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the front view of the preferred lettering pen of the utility model.
Fig. 2 is the exploded view of lettering pen in Fig. 1
Fig. 3 is the sectional view of lettering pen in Fig. 1.
Description of reference numerals: 1, nib, 2, point cover, 3, connector, 4, sheath, 5, oil pipe, 6, air bag.
Detailed description of the invention
In figure 3; connector (3) one end is connected with nib (1), and through point cover (2), point cover (2) can move axially; point is overlapped (2) and pushes nib (1) to, nib can be protected as the cap for brush.When writing, point is overlapped (2) upwards to push away and can expose nib (1).
Sheath (4) is a spaghetti, increase the comfort level held a pen, sheath (4) is stuck on the step that connector (3) and oil pipe (5) formed, increase stability, connector (3) can eject from oil pipe (5) by sheath (4), convenient to oil pipe (5) filling ink.
Air bag (6) is bonded on oil pipe (5) inwall.The material of air bag (6) is soft film, volume size is along with air pressure change, air bag (6) external diameter equals pipe aperture, and the length of air bag (6) gets the difference that tubing length subtracts connector connected component length, can obtain maximum air pressure adjustment so interval.
Connected mode in above-mentioned example can adopt and be fastenedly connected, and is threaded or other mechanical connection manners.Other state can also be presented according to lettering pen of the present utility model, do not enumerate at this.
Although preferred embodiment discloses as above by the utility model; so itself and be not used to limit the utility model; those of ordinary skill in the art; on the basis understanding basic conception of the present utility model; some similar adjustment and amendments can also be made; and these adjustment and amendment, all should think and belong within the claimed scope of the utility model.
